Title: Target of x-ray tube and its manufacturing method
Inventor: ANDO MASAMI
IPC: H01J9/14
Filed: 2002-06-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a practical target of an X-ray tube capable of generating a characteristic X-ray of lanthanoid with sufficient intensity, and to provide its manufacturing method.  <P>SOLUTION: A substance prepared by infiltrating copper into a sintered compact of a boride or a carbide of lanthanoid is used as an X-ray generation material. For instance, a material prepared by impregnating copper into a sintered body of lanthanum hexaboride is used. As its manufacturing method, first a void 14 is formed in a block 12 of copper, and the sintered compact 10 of lanthanum hexaboride is disposed in the void 14. The copper block 12 is put into a capsule 18 of stainless steel and thereafter heated to a temperature above the melting point of copper in a pressurized atmosphere to melt the copper block 12. Thereby, copper is infiltrated into the sintered compact 10. Thereafter a flake 50 is sliced off the sintered compact 10 and bonded to the target 62 of an X-ray tube.  <P>COPYRIGHT: (C)2004,JPO

Title: Substrate processing device
Inventor: HAYASHI AKINARI
IPC: H01L21/205
Filed: 2002-06-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a substrate processing device which can efficiently cool a shutter for shutting a treating chamber.  <P>SOLUTION: In a CVD device comprising a treatment chamber 14 for heat-treating wafers 1, the shutter 30 for shutting a furnace opening 15 of the treating chamber 14 during idling operation, and a cooling water path 32 which is arranged in the shutter 30 and in which the cooling water 31 is made to flow, the cooling water path 32 is structured so that the cooling water 31 is made to flow initially into the central part of the shutter 30, and then made to flow into the peripheral part of the shutter 30. The cross section of the cooling water path 32 is the same along the whole length and is composed of a curved shape. Since fresh water, having high cooling efficiency is fed initially to the central part having high heat-receiving efficiency and poor heat-radiating efficiency, and subsequently fed to the peripheral part having a low heat receiving efficiency and a high heat radiating efficiency, the shutter is cooled efficiently. Additionally, since the cooling water can be prevented from staying, deterioration in the cooling performance in the cooling path can be prevented.  <P>COPYRIGHT: (C)2004,JPO
